Recent research, however, indicates variation rather than absence. A study done in 2008 by Emmanuele Jannini and colleagues at the University of L’Aquila in Italy used ultrasound to measure anatomical differences between women who report vaginal orgasms (orgasm due to stimulation of the vaginal walls and not the clitoris) and those who don’t. The researchers scanned the genital area of nine women who reported vaginal orgasms and eleven who didn’t and found that those with orgasms have thicker tissue in the “urethrovaginal space.” The authors conclude that the size of this space is correlated with the ability to have a vaginally-activated orgasm; without evidence of what they call the G-spot, women won’t have this type of orgasm.
However, critics on both sides of the debate question the results of this small study. G-spot detractors contend that this place could just be an extension of the clitoris, which was found in 1998 by Helen O’Connell to be much larger than previously thought—the part we can see externally is really just the tip of the iceberg. Because the clitoris extends all the way into the vagina, perhaps vaginal orgasms occur because they are actually stimulating the part of the clitoris, or the glands, nerves, and tissue surrounding this area.
On the other side of the debate are the G-spot believers who question why the study showed only some women to have G-spots and not all.
Prostate and Ejaculation, for Women?
Part of the confusion regarding the G-spot may also have to do with the unclear characterization of female “ejaculation” and the Skene’s glands. The Skene’s glands are paraurethral glands thought to be homologous to the male prostate, and are sometimes referred to as the female prostate.
Some researchers claim that the Skene’s glands and the G-spot work in conjunction—or perhaps are one in the same. According to the Kinsey Institute, during sexual arousal, the vagina and the Skene’s glands swell so that you can feel them in the interior of the vagina—around the same area that the G spot is supposed to be. For some women, pressure here is pleasurable; for others it is not.
Stimulation of this area in some women can cause the Skene’s glands to produce fluid, like its homologous male counterpart. In men, the prostate produces secretions, which mix with sperm to produce semen. In some women, the Skene’s glands may produce the fluid that is the source of female ejaculate. Although it comes out the urethra, the ejaculate is not urine. Biochemical analysis shows the presence of prostatic acid phosphatase and prostate specific antigen, further indicating the role of a prostate-like structure in women.
